Maybe changing the perspective on the original Legend of Zelda is a little weird -- everything looks so different here -- but that's exactly what makes this Oculus Rift version of the game interesting. Its almost like you're playing (or in this case, watching) an entirely new game.
Right now, this version of Zelda is in beta according to Vaecon -- and only the overworld and first dungeon are available. The full version of the game drops on March 2014. For now, you can download the beta version of the game for the Oculus Rift here.
And when you're done with that, remember: you can also play Zelda II as a first person shooter too.
